There have been some valuable studies in the literature on characterizing
off-path SmartNIC [1]}, [2]}, [3]}, [4]}.
However, the extensively studied part is its offloading computation capabilities.
A main finding from them is that the computing power of SmartNIC
is wimpier than the host [1]}, [2]}, [3]}.
As a result, off-path SmartNIC does not improve the speed of a single network path,
e.g., NIC to the host.
For example, iPipe [1]} shows that the path between host and SoC has
a relative high latency due to the support for more developer-friendly RDMA.
